Canada's Office of the Superintendent of Financial Institutions has issued a regulatory notice containing a reminder that there are a number of reserved words, particularly those relating to banking, which may not be used without authority, in relation to financial services. It goes far beyond the use of the words in the name of businesses and will tighten up sloppy language in marketing and so-called social media. It might, also, inadvertently, make the point that "fintech" companies are not banks and do not afford consumers the protection that governments provide to bank depositors.
